4. The greenhouse gas emissions and energy consumption of
the Helsinki Metropolitan Area are increasing more rapidly
than its population
•The millionth inhabitant
30.4.2007.
•The growth of population
nearly 1% per year.
•Total GHG-emissions
increased 12 % between
2000 and 2004
•Traffic volumes of the
region are growing heavily

5. Consumption-based greenhouse gas emissions in
the Helsinki Metropolitan Area
The main sources of emissions are:
heating 43 %,
electricity consumption 28 %
transport 23 %

9. Proposal for a climate vision for the Helsinki
Metropolitan Area
Improved energy efficiency and the
sparing use of natural resources
leads to a fall in greenhouse gas
emissions in the region and to
improved competitiveness.
This main vision is supplemented by
six sectoral visions concerning:
•
Transport
•
Land use
•
Construction and buildings
•
Electricity
•
Energy generation
•
Consumption and waste

10. The target and trends in greenhouse gas emissions
in the Helsinki Metropolitan Area
The target is to reduce per capita energy consumption in the metropolitan area
over the period 1990–2030 to minimize GHG emissions:
•from 6.3t CO2 eqv in 2004 to 4.3t CO2 eqv in 2030 per capita.
•by 39% over the period 1990 –2030.

11. Vision and operating policies for transport
Greenhouse gas emissions from transport have fallen by at least
20 per cent. Public transport, walking and cycling are the
preferred forms of mobility.
Influencing demand for transport and patterns of mobility
by improving the status and service standards of public
transport, walking and cycling.
- through mobility service pricing,
Cutting emissions from city transport operation
- through the use of low-emission standards
Promoting the use of low-emission vehicles through
- economic guidance in favour of low-emission vehicles
- environmental zones based on motor vehicle emissions

12. Reducing public transport emissions with the help
of a new fuel:
•The providers of public transport and Neste Oil have signed a letter of intent
aiming at using NExBTL biofuel to power buses and waste disposal trucks.
•300 buses will start using the fuel in August 07 and the aim is that in 2008
half of the buses will use synthetic biodiesel
•Biodiesel (100%) will reduce emissions from buses by half
•An obligation to use biofuels to be introduced
in fuel distribution at the turn of the year
2007/2008.
•A tax relief from the state would
encourage the use.

14. Operating policies for construction and buildings
Improving energy efficiency in new buildings
new technology pilot projects e.g. low-energy buildings
Improving energy efficiency in the existing buildings
new renovation technology
Guiding choices of heating and cooling systems
impact of various heating and cooling methods
improving various financing and grant procedures
Improving maintenance
retraining building service staff
active use of servicing logbooks
improving consumption metering to ensure that A solar heated building
energy costs can be allocated to the end consumer in Viikki, Helsinki
new control and guidance technology for information
YTV 13.6.2007
15. Operating policies for electricity consumption
Improving city procurement procedures in support
of higher energy efficiency
- introducing the latest technology for street lighting
and illumination control systems
Improving allocation of energy costs to the
consumer and associated information gathering
- enhancing and extending the scope of electricity
consumption metering
- ensuring energy bills based on actual consumption
Information
- information campaigns and guidelines for saving

16. Operating policies for energy generating and
distribution
Benefiting from the opportunities of a more
compact urban structure
- optimising the benefits of cogeneration
- investigating the use of district heating return flows (e.g.
low energy sites, wastewater sludge heating, cooling)
- investigating waste heat sites and heat recovery
prospects at small (e.g. condensation heat from ice rink
refrigeration) and large (e.g. wastewater treatment plants)
sites
- auditing, energy reviews and suggestion prizes
- extending district cooling networks and replacing
separate cooling installations in buildings
YTV 13.6.2007
17. Operating policies for energy generating and distribution
• Centralised energy generation falls wholly within the scope of
increasingly strict emissions trading rules
- promoting use of renewable energy sources
- promoting use of clean technology for coal
and natural gas
- replacing some coal and natural gas with fuels
of waste origin and electric power generated
from renewable energy sources
• Promoting eco-efficiency of decentralised
energy generation and increasing use of
renewable energy sources Vuosaari B, the largest natural gas-fired
combined heat and power plant in the

18. Possible Top 10 areas for action
•Energy consumption and GHG emissions in all the municipalities
within the metropolitan area
•Public sector procurement procedures
•Replacing coal with recovered fuels and eco-electricity
•Energy efficiency at all levels
•Rail traffic and vehicle biofuels
•Heating systems of detached houses
•Information
•Motivating people to save energy
•Promoting life-cycle thinking and
developing eco-areas
•Monitoring and statistics
